Basically, on /r/me_irl a few days ago, someone posted an image of a PowerPoint saying "In Conclusion, bionicles", with an image of the Toa Mata. Then, people got hit with a wave of nostalgia and began posting their own BIONICLE memes....

And then it spiraled out of control. It's really nice to see BIONICLE getting some kind of attention, even if just in the form of memes on Reddit.
